//  Interrupt BSP callback functions. OMAP3 SoC has one external interrupt
//  pin. In general solution it can be used for cascade interrupt controller.
//  However in most cases it will be used as simple interrupt input. To avoid
//  unnecessary penalty not all BSPIntrXXXX functions are called by default
//  OMAP3 interrupt module implementation.
